PLOW-WHEEL BOX.

SPECIFICATION forming part of Letters Patent N 0. 609,713, dated August 23, 1898. Application filed January 6,1898. as a. 665,800. (No model.)

To aZZ whom it may concern:

Be it known that I, CALVIN P. WAKEFIELD, a citizen of the United States, residing at Livingston, in the county of Merced and State of California, have invented certain new and useful Improvements in Plow-Wheel Boxes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to wheels for plows, and, among other things, it contemplates the provision of a plow-wheel having an axle-box which when placed on an 'axle is adapted to effectually exclude sand and grit from its interior, and thereby prevent undue wear of the bearing and prolong the usefulness of both axle-box and axle.

The invention will be fully understood from the following description and claims when taken in conjunction with the annexed drawings, in which Figure 1 is a perspective View of a portion of a gang-plow frame equipped with one of my improved wheels. Fig. 2 is an enlarged diametrical section showing the axle-box of the Wheel on the axle or axle-pin and the latter as connected to the hanger of the frame. Fig. 3 is a perspective View of the axle-box on the axle or axle-pin, and Fig. 4 is a transverse section taken in the plane indicated by the line a; a: of Fig. 2.

In the said drawings similar letters designate corresponding parts in all of the several views, referring to which- A designates a portion of the frame of a gang-plow.

B designates a hanger connected to and depending from the frame and having an aperture a, which is preferably square, as shown.

C designates an axle which is headed at one end, as indicated by l), and has the square portion 0 adapted to rest in the aperture a of the hanger and the threaded end at to receive a nut c, and D designates my improved wheel, which is preferably formed of metal. This wheel D comprises a hub f, spokes g, and a rim h, which are cast or otherwise formed in one piece, and the axle-box E. (Better shown in Fig. 2.) The said box E rests in the hub f and is provided with the peripheral flange j, which is connected, preferably in a detachable manner, to the hub through the medium of the bolts 7o, as shown. Said box E is also provided with a longitudinal central bore Z and a recess m at the inner end of the same, and is further provided with an enlargement n on the flange j and a radial passage 13, which extends through said enlargement n to the bore Z and is designed to convey lubricant to said bore.

F designates a cap which receives the outer end of the box and is secured thereon by a set-screw g.

G designates a cap which is mounted on the square portion 0 of the axle between the innerend of the box and the hanger B and :loosely receives the inner end of said box, and H designates a washer of metal or other suitable material, which is mounted on the square'portion of the axle, so as to turn there with, and is arranged in the recess m at the inner end of the box, as shown.

. The caps F and G tend to prevent the en try of sand, grit, and the like into the interior of the box, while the washer H, being beveled, as indicated by z", and having its outer side flush with the end of the box, will cause the dust and the oil with which it is mingled to work toward the inner end of the box and out of the same into the cap G. To facilitate the escape of such commingled oil and dirt, the cap G is provided at its under side with the notch I, through which the oil and dirt worked back by the washer II will find ready passage out of the box.

In practice the parts of my improvements are assembled on the axle, and thesaid axle is then connected to the hanger of the plowframe by placing the square portion 0 of the axle in the aperture a of the hanger and mounting the nut e on the threaded end of the axle. From this it will be appreciated that the axle and the wheel thereon may be readily disconnected from the plow-frame and that when so disconnected the caps F and G, as well as the axle, may be readily removed from the box to permit of all ofthe parts be ing readily cleaned. It will also be observed that in the event of the box wearing out before the remainder of the wheel it may be readily removed and replaced by a new box, and this without the employment of skilled abor.

I prefer in practice to form my improved wheel entirely of metal; but it is obvious that when desired the hub, spokes, and rim may be of wood, in which case the latter would be provided with a suitable tire.

The box of my improved Wheel, notwithstanding its simplicity, will effectually exclude fine dust and grit from the bearing, and it will therefore be appreciated that the wheel is especially adapted for use. on plows employed in light and sandy soils. The wheel, however, may be used to advantage on plows used in various kinds of soil, as the box will prevent wear of the bearing and will insure the easy running of the wheel at all times.

Having thus described my invention, what I claim ise l 1. The combination of an axle having an angular portion at the inner end of its spindie, a wheel having a box provided with a bore receiving the axle and also provided with a recess at the inner end of said bore, the washer mounted on the angular portion of the axle and arranged Within the recess of the box and having its outer side beveled, and the cap mounted on the angular portion of the axle and snugly receiving the inner end of the box and having the notch in its under side, substantially as specified.

2. The combination of an axle having a head at the outer end of its spindle and an angular portion at the inner end of the same terminating in a threaded end adapted to receive a nut, a wheel having a box provided with abore receiving the axle and also provided with a recess at the inner end of said bore, the washer mounted on the angular portion of the axle and arranged within the recess of the box and having its outer side beveled, the cap mounted on the angular portion of the axle and snugly receiving the inner end of the box and having the notch in its under side, and a cap resting over the outer ends of the axle and box and secured upon the latter, substantially as specified.

3. -The combination of an axle having a head at the outer end of its spindle and an angular portion at the inner end of the same terminating in a threaded end adapted to receive a nut, a wheel having a box provided with a bore receiving the axle, a cap mounted on the angular portion of the axle and snugly receiving the inner end of the box, and a cap resting over the outer ends of the axle and box and secured upon the latter, substantially as specified.

In testimony whereof I aflix my signature in presence of two Witnesses.

CALVIN P. WAKEFIELD.
